Suggested Answer:

Box 1: New-CsTeamsTranslationRule
The New-CsTeamsTranslationRule cmdlet to create a new telephone number manipulation rule.
Example:
New-CsTeamsTranslationRule -Identity 'AddPlus1' -Pattern '^(\d{10})$' -Translation '+1$1'
This example creates a rule that strips +1 from any E.164 eleven digits number. For example, +12065555555 will be translated to 206555555
Example 2:
New-CsTeamsTranslationRule -Identity 'StripE164SeattleAreaCode' -Pattern '^\+1206555(\d{4})$' -Translation '$1'
This example creates a rule that strips +1206555 from any E.164 ten digits number. For example, +12065555555 will be translated to 5555
Box 2: '^\+61(\d{9})$'
Strip out +61. Keep 9 digits.
Note: You are opening a new warehouse site in Melbourne. The new warehouse will connect to a phone carrier by using a Session Border Controller (SBC).
Dialing rules are an area code of two digits beginning with a zero followed by a subscriber number of eight digits. For example, an E.164 number of
+61370105550 will be translated to 03 7010 5550 and +61255505550 will be translated to 02 5550 5550.

Can someone explain this example for me? For example, an E.164 number of +61370105550 will be translated to 03 7010 5550 and +61255505550 will be translated to 02 5550 5550. The suggested answer is ^\+61(\d{9})$ to strip +61 from the full number and keep 9 digits. With the $1 translation to me this means +61370105550 will be translated to: 3 7010 5550 Or am I wrong here? To me the question is wrong, or has something missing, should the translation rule not be 0$1 to make it 03 7010 5550?

https://blog.insycle.com/phone-number-formatting-crm - "In many countries including the UK, a “0” is placed at the beginning of the area code and subscriber number. With E.164, the “0” is typically removed, with a “+” and the international country code added before the area code." answer with ^\61(\d{10})$
